One of my pet peeves is that my kids often don't put away DVDs and CDs. I'm constantly finding bare ones floating around the house and getting scratched up, and it drives me nuts.
All last year, whenever I found a bare disc, I took it and hid it in my closet. I was hoping this would help people remember to put them away. Maybe it helped a little, but not much. I guess we have so many movies to watch and computer games to play that they didn't really miss the ones I confiscated.
So I gave up on that, and now I'm just saying, "To hell with it." I bought one of those machines that buffs away the skips, and I suppose I'll treat their discs if they ever ask, but otherwise I guess I just don't give a damn anymore.
